HARNESS HOOK roR Looms.

Application filed November 25, 1927. Serial No. 235,608.

lVIy invention relates to a harness hook which is adapted to support a series of harnosses within the loom. I have found that by the use of a specially constructed hook that it, is possible to support a series of harnesses from one strap; In present practice it is usual to employ a separate hook for each harness and in said cases as many two harnesses are supported from one book, but this is not satisfactory inasmuch as 'the hefoks leading t'o'th'e harnesses hare at'n'dency to crawl tip the sides of the a rciiate b'ase'of the hook which is secured to t'he harness strap: This tendency is a serious drawback in that-it causes ,cro'wding of theharne'sss with the result that are yarn iife'ars out and the ends are easily brakes. In the weavipg of cloth a better result is generally obtained if the harnesses theselies which alternate in their reciprocttt bry mdvemente're ea'chdisposcd a little distance above the other in a graded relation as a greater clearance, is given and less tensibn placed (in the yarn. I have found that; By the use of a hook having a substanti'ally triangular contour with hooks of progressively varying lengths disposed on the herizo'ntal barthat the graded relation of the harnesses is obtained without any crowdmg of the harnesses together.

It is an object of my invention to pro dil c'e a harness hook for use in loonis which is simple in structure and reliable in opera t'lo'ri.

Another object of my invention is to proi'ide a harness hook of a substantially triangular contour having hooks thereon which are secured to the harnesses and are adapted to maintain the harnesses in a graded relation without any tendency to crowd together.

Still another object of my invention is to provide a harness hook which is capable of supporting several harness menibers wherebj tlie straps, rollers, hooks and jacks that are necessary to support the harness memhers are greatly reduced in number thereby causing a great saving. This is made possible by reason of the "fact that one hook does-the Work of two or more.

Other objects and advantages will appear from the following detailed description taken in connection with the accompanying drawillgs.

I attain these objects and advantages by means of the mechanism illustrated in the drawings wherein:

Figure l is a front elevation'al view of the upper portion of a loom showing the loom arch together, with the harness straps and, the improved harness hooks with sufiicient .of the harnesses being shown to illustrate the mode of attachment.

Figure2 is an elevational View of the lower part of the harnesses showin'gthe mode of attachment of the hooks to the harnessos and from the harnesses to the treadlc means through the jacks and straps.

Figures 3 and 4 are front and side elevation'al views of the, complementary harness hooks. the upper series of hooks being used to secure the. upper part of the harnesses w ere'as the lower series is secured to the lower part of the harnesses. It is to be noted that the upper hook is provided with an enlarged opening for the reception of the strap whereas the lower hookis proi 'idcd with a screw end for its insertion into the jack.

Similar numerals refer to similar parts throughout the several Views.

Referring to the drawings, 1 is a loom arch having the bearings 2 on wh ch the shaft 3 is supported. Mounted on the shaft 3 are the rollers 4 having straps 5 secured thereto by the screws 6. 'lho other ends of the straps are provided with a clip 7 which is adapted to fit within notches 8 provided on the strap for the purpose of adjustment. Harness hooks are attached to the ends of the straps for supporting the harnesses S) and 10. As shown in the drawings the harnesses are in series of three.

The hooks, by means of which these har nesses are attached to the straps, form the distinctive feature of this invention, and, as may be seen from Figures 3 and 4 of the drawings, the upper hook comprises essentially a shank i0 liavin the triangular loops 11 and 12 disposed at right angles to each other and integral with said shank. This, of course. niay be manufactured by twisting the wire into the necessary form and as the method for doing such is familiar to anjx one skilled in the art. no discussion will be here made as to the mode of manufacture.

The upper lo op is adapted to receive the strapii by which the saine is suspended from the shaft 3. Mounted on the lov 12 are the hooks 13, 14, 15 which, as may be seen from the drawings, are graded in length. The lower hook which is attached to the lower part of the harnesses, as shown in Figure 2, comprises a triangular loop .l6 hav'ng a screw stem 17 which may be inserted into the jacks '21. Hooks 18, 19. 20 of the same size as 13, 14, 15, but reversed as to position thereto so that the longest hook in one series opposes the shortest hook in the other series as shown clearly in Figure 4. The turned up portions of the hook which catch in the hook eyes 9 on the harness frames are'at right angles to the horizontal portion of the lower loop 1". In Figure 2 the mode of attachment of the lower hook is shown clearly, the hooks being secured to hook eyes on the lower. bar of the harness frames and are secured to the jacks 21. The jacks in turn are strapped to the treadles 22 by means of the straps 23.

Reverting to the particular structure of the harness hookit should be noted that the horizontal portion of the lops12 and 16 to which the hooks 13, 14, and 18, 19, are secured is of such construction as to allow the hooks complete freedom of movement in a horizontal direction without any tendency to crawl up the sides or to become bunched together. This differs greatly from the hooks now in use which have a circular loop for holding the individual harness hooks which by reason of the arcuate base, in cases where two or more hooks are used, causes the hooks to climb up the sides whereupon the harnesses hang together. Because of this limitation in the hook now in general use no more than two individual hooks are mounted on the same hook attached to the strap and where it is necessary to hook up three harnesses to work at the same time extra straps, rollers and jacks are necessary. It will be appreciated that with the applicants proposed hook in the ordinaryloom having six harnesses and assuming that two harnesses are attached to one hook that the substitution of applicants hook will eliminate the need for four rollers, six straps, two jacks and four hooks which is an immense saving as to materials. In other words, in the construction now to be found it is customary to join two harnesses to one hook and the third harness to anothcr hook so that four sets of hooks are necessary for securing the two series of harnesses to the straps.

All that has been said above in the description of my preferred embodiment is offered by way of illustration and not limitation. I do not wish to be limited to the exact structure of the preferred embodiment shown and described, or to any particular material used in the construction of parts, or to the design of parts, but desire protection as against any variations in structure which utilize the principle of my invention and fall within the harness hook comprising in combination purview of my invention and are within the spirit and scope of the following claims The invention having been set forth, what is claimed as new and useful is:

1. In combination with a loom l'iaving series of harnesses, harness straps, jacks,

put-=2:

wire member, said wire member having shank portion, said wire member having loop formed at one end thereof, means at the other end of said shank for attachment to either a harness strap or a jack, said loop having a horizontal portion, a plurality of individual hooks on said horizontal portion for holding said harnesses, said horizontal portion being of sufiicient length to provide clearance for said individual books.

2. In a loom having harness members, har-. ness straps, treadles, jacks, complementary hook members for supporting said harness members comprising a top hook member attached at one end to one of said harness straps, said top hook member having a substantially triangular loop at its other end, a plurality of individual hook members for each ofsaid harness members disposed on the horizontal portion of said loop, said harness members being secured at their bottom portions by a bottom hook member, said bottom hook member comprising means at one end for securing same to one of said jacks, a substantially triangular loop at the other end having a plurality of individual hooks corresponding to said first mentioned disposed individual hooks and coacting therewith on its horizontal port-ion, said top and bottom hook members being adapted to secure a plurality of said harnesses from one leather strap and one jack, the harness members being restrained against banging together.

3. In combination with a loom having series of harnesses, harness straps, jacks, harness hook comprising in combination wire member, said wire member having shank portion, said wire member having loop formed at one end thereof, means at the other end of said shank for attachment to either a harness strap or a jack, said loop having a horizontal portion, a plurality of individual hooks on said horizontal portion for holding said harnesses, said horizontal portion being of suiiicient length to provide clearance for said individual hooks, said individual hooks being of progressively varying lengths to hold said harnesses in a graded relation.

4. In a loom having harness members, harness straps, treadles, jacks, complementary hook members for supporting said harness members comprising a top hook member at tached at one end to one of said harness straps, said top hook member having a substantially triangular loop at its other end,

a plurality of individual hook members for each of said harness members disposed on the horizontal portion of said loop, said harness members being secured at their bottom portions by a bottom hook member, said bottom hook member comprising means at one end for'securing same to one of said jacks, a substantially triangular loop at the other end having a plurality of individual hooks corresponding to said first mentioned disposed individual hooks and coacting therewith on its horizontal portion, said top and bottom hook members being adapted to secure a plurality of said harnesses from one leather strap and one jack, the harness members being restrained against banging together, said individual hooks on the top and bottom hook members being of progressively varying length, the longest hook in the top series 0pposing the shortest hook in the lower series and conversely, whereby the harness members are held in a graded relation to give more clearance during the operation of the same.

In testimony whereof I have afiixed my signature.
